It’s been 24 hours of Manjaro on my XPS 17 9700 and I’m still unable to get the audio working. From what I can see this appears to be a known issue with no solution yet, but I wanted to check in on my own post just in case.
I have tried both of the grub modifications
snd-intel-dspcfg.dsp_driver=1 in the grub config file, and have also tried kernels 5.4.64-1, 5.8.6-1, and 5.9 experimental. I installed the sof-firmware drivers too, which also had no effect. I am pretty new to linux so unfortunately it feels like I’m taking a bit of a shotgun approach here.
I have read that PulseAudio 14 might be coming with a fix for this, but at this point I am not sure where the incompatibility lies and where the patch will ultimately come from!
Any and all information is greatly appreciated. Thank you!
